Catharanthus lanceus, commonly known as Madagascar Periwinkle, is a captivating plant that boasts distinct botanical characteristics. Native to Madagascar, this evergreen perennial belongs to the Apocynaceae family, which is known for its diverse array of flowering plant
Catharanthus lanceus typically grows as an erect, branching shrub with woody stems that can reach a height of about 1 to 1.5 meters. The stems are covered in smooth, glossy bark and are often tinged with reddish hues.
The leaves of Catharanthus lanceus are simple, opposite, and ovate to elliptic in shape. They have a smooth texture and are characterized by their glossy, dark green color. The leaves are arranged in pairs along the stems and emit a pleasant fragrance when crushed.
The most striking feature of Catharanthus lanceus is its eye-catching flowers. The flowers are solitary and terminal, meaning they emerge at the tips of the stems.
They are funnel-shaped with five distinct petals and can come in a variety of colors, including shades of pink, white, lavender, and even bi-colored combinations.
The center of the flower features a contrasting throat with a darker color. The flowers are not only visually appealing but also play a crucial role in the plant’s reproduction.
Catharanthus lanceus produces flowers in clusters known as cymes. These cymes consist of multiple individual flowers grouped together at the ends of the stems. The cymes create a stunning display of color and add to the overall ornamental value of the plant.
After successful pollination, the flowers give way to small, elongated seed capsules. These capsules contain the plant’s seeds and gradually develop as the flowers fade. The seed capsules split open when mature, releasing the seeds for potential propagation.
Catharanthus lanceus thrives in tropical and subtropical climates, making its home in Madagascar and other regions with similar environmental conditions.
It is commonly grown as an ornamental plant in gardens, parks, and landscapes due to its vibrant flowers and glossy leaves. The plant’s adaptability to various soil types and its ability to tolerate some drought make it a popular choice for landscaping.
Catharanthus lanceus has a rich history of traditional medicinal uses. Its extracts have been utilized in various cultures for their potential healing properties, including managing diabetes, treating wounds, and supporting overall wellness.

The Methods of Usage to Achieve the Provided Health Benefits of Catharanthus lanceus (Madagascar Periwinkle)
1. Herbal Tea: Prepare a soothing herbal tea by steeping dried Catharanthus lanceus leaves in hot water. This simple method allows you to extract the plant’s beneficial compounds and create a flavorful infusion.
To make the tea, place a teaspoon of dried leaves in a cup of hot water and let it steep for about 5-10 minutes. Strain and enjoy your herbal tea daily to experience its health-promoting effects.
2. Topical Application: For external use, you can create an infused oil or salve using the plant’s extracts. This method is particularly beneficial for addressing skin issues, wounds, or sore muscles.
To make an infused oil, gently heat a carrier oil like coconut or olive oil and add dried Catharanthus lanceus flowers or leaves. Let the mixture infuse over low heat for several hours, then strain the oil and store it in a dark glass bottle. Apply the infused oil topically to the affected area as needed.
3. Tinctures: Tinctures are concentrated liquid extracts that are easy to take orally. To create a Catharanthus lanceus tincture, you’ll need dried plant material and alcohol (such as vodka or grain alcohol).
Fill a glass jar with the dried leaves, flowers, or a combination of both, and cover them with the alcohol. Seal the jar and let the mixture sit in a cool, dark place for a few weeks, shaking it gently every day.
After the maceration period, strain the liquid and store it in a labeled tincture bottle. Take a few drops of the tincture diluted in water as directed by a healthcare professional.
4. Powdered Extract: Another method is to create a powdered extract from the dried Catharanthus lanceus plant material.
This can be done by grinding the dried leaves, stems, or flowers into a fine powder using a mortar and pestle or a grinder. The resulting powder can be encapsulated for convenient consumption, added to smoothies, or mixed with a carrier substance like honey.

Scientific Evidence and Case Studies on Catharanthus lanceus (Madagascar Periwinkle)
1. Antidiabetic Properties: A study by Espejel-Nava et al. (2018) found that a phenolic fraction from Catharanthus roseus stems, closely related to Catharanthus lanceus, decreased glycemia and stimulated insulin secretion in diabetic models. This suggests potential antidiabetic benefits for similar compounds in C. lanceus (Espejel-Nava, J. A., Vega-Avila, E., Alarcon-Aguilar, F., et al., 2018).
2. Antioxidant Activity: Ferreres et al. (2008) investigated Catharanthus roseus and identified new phenolic compounds with significant antioxidant potential. These findings likely apply to C. lanceus due to its similar alkaloid profile, supporting its role in reducing oxidative stress (Ferreres, F., Pereira, D. M., Valentão, P., et al., 2008).
3. Anticancer Potential: Moon et al. (2018) explored Catharanthus roseus cambium meristematic stem cell cultures and found bioactive compounds with anticancer activities. Given the shared vindoline-type alkaloids in C. lanceus, this suggests potential anticancer properties (Moon, S. H., Pandurangan, M., Kim, D. H., et al., 2018).
4. Antimicrobial Effects: Gupta et al. (2015) demonstrated that green ZnO nanoparticles from Catharanthus roseus, which shares chemical similarities with C. lanceus, exhibited effective antimicrobial activity against various pathogens. This supports the plant’s traditional use in infection treatment (Gupta, M., Tomar, R. S., Kaushik, S., et al., 2015).
These studies underscore the therapeutic potential of Catharanthus lanceus, particularly in managing diabetes, oxidative stress, cancer, and infections, though further research specific to this species is needed.
